N = 1024; n = 0:N-1; w0 = 2*pi/5; x = sin (w0*n)+10*sin (2*w0*n); Compute the short-time Fourier transform using the function defaults. Plot the spectrogram. s = spectrogram (x); spectrogram (x, 'yaxis') Repeat the computation. Divide the signal into sections of length n s c = ⌊ N x / 4. 5 ⌋.
Mel spectrogram - MATLAB melSpectrogram
https://www.mathworks.com/help/audio/ref/melspectrogram.html
Use the default settings to calculate the mel spectrogram for an entire audio file. Print the number of bandpass filters in the filter bank and the number of frames in the mel spectrogram. [audioIn,fs] = audioread( 'Counting-16-44p1-mono-15secs.wav' ); S = melSpectrogram(audioIn,fs); [numBands,numFrames] = size(S); fprintf( "Number of bandpass filters in filterbank: %d\n" …
How to generate the spectrogram of a wav file in Matlab ...
https://stackoverflow.com/questions/38359735/how-to-generate-the-spectrogram-of-a-wav-file-in-matlab-with-frequency-on-the-x
My code which generates the spectrogram with the frequency on the y-axis and the time on the x-axis (Matlab code): [song, fs] = wavread ('filename.wav'); windowSize = 256; windowOverlap = []; freqRange = 0:300; spectrogram (song, windowSize, windowOverlap, freqRange, fs, 'yaxis');

Reconstruction of audio signal from Spectrogram - Signal ...
https://dsp.stackexchange.com/questions/9877/reconstruction-of-audio-signal-from-spectrogram
I would like to convert this spectrogram back to the audio signal and play it, so that I would be able to know when reconstructed from lower dimensions, how does the audio sound. Is there any function available in say Matlab. to convert a magnitude Spectrogram to an audio signal ??
